Methods and apparatus are disclosed for using long exposure video for virtual reality headsets. An example apparatus includes a video camera to capture first, real time video of a scene using a first field of view while operating using a first exposure time, the first exposure time corresponding to a normal exposure time of a human eye; a transformer to transform the first, real time video into a second video corresponding to a second exposure time, the second exposure time being at least twice as long as the first exposure time; and a display to display the second video at the second exposure time.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The video apparatus as defined in claim 1, further including a field of view reducer to process the first video into the second video after capture of the first video, the second video exhibiting a second field of view different from the first field of view, the first field of view wider than the second field of view.
3. The video apparatus as defined in claim 2, wherein the display has a displayed field of view of the scene, the displayed field of view corresponding to the second field of view.
4. The video apparatus as defined in claim 3, wherein the field of view reducer is to reduce the first field of view of the first video in accordance with the displayed field of view of the display.
9. The video apparatus as defined in claim 1, wherein the display is coupled with the video camera to display the second video in substantially real time with respect to the first, real time video.
10. The video apparatus as defined in claim 1, wherein the video camera is a head mounted video camera mounted via a gimbal to ensure stability during capture of the first video of the scene.
12. The non-transitory machine readable medium as defined in claim 11, wherein the instructions cause the machine to process the first video into the second video after capture of the first video, the second video exhibiting a second field of view different from the first field of view, the first field of wider than the second field of view.
13. The non-transitory machine readable medium as defined in claim 12, wherein the instructions cause the machine to display the second video on an interface, the interface having a displayed field of view of the scene, the displayed field of view corresponding to the second field of view.
14. The non-transitory machine readable medium as defined in claim 13, wherein the instructions cause the machine to reduce the first field of view of the first video in accordance with the displayed field of view of the display.
19. The non-transitory machine readable medium as defined in claim 11, wherein the instructions cause the machine to display the second video in substantially real time as the first, real time video is being captured.
21. The video apparatus as defined in claim 20, further including means for processing the first video into the second video after capture of the first video, the second video exhibiting a second field of view different from the first field of view, the first field of view wider than the second field of view.
22. The video apparatus as defined in claim 21, wherein the means for displaying corresponds to a displayed field of view of the scene, the displayed field of view corresponding to the second field of view.
23. The video apparatus as defined in claim 22, wherein the means for processing the first video is to reduce the first field of view of the first video in accordance with the displayed field of view of the means for displaying.
